Macbook - How To Disable Overheat Shut Down

I am trying to use my macbook without a fan inside off it ( please dont ask why )
and i cant seem to find out how to disable the prefrence or the part that is controlling this

How can i disable this so i can use my mac again ? the fan is broken so i need to get this working, my macbook ( old white ) that i used to have, dident have any issues like this after taking the fan away from the mainboard, so it has to be a setting somewhere
